摘要： PCT No. PCT/DE98/02182 Sec. 371 Date Jun. 1, 1999 Sec. 102(e) Date Jun. 1, 1999 PCT Filed Jul. 30, 1998 PCT Pub. No. WO99/16635 PCT Pub. Date Apr. 8, 1999The invention relates to an adjustment of the transmission ratio of a transmission having a primary end and a secondary end. The transmission is continuously variably adjusted with respect to its transmission ratio and is mounted between a vehicle engine and the drive wheels. According to the invention, means are provided by means of which a deceleration state of the vehicle of a pregivable or pregiven extent is determined. The output rpm of the vehicle engine is adjusted or controlled in dependence upon the detected rpm of the primary end in response to the determination of one such deceleration state. With the invention, it can be ensured that the vehicle with a CVT transmission comes to standstill for a transmission ratio close to the start transmission ratio even for especially intense decelerations at low speeds (30 to 60 km/hour). Furthermore, the engine can be fired with fuel in order to increase the volumetric displacement of the hydraulic pump without the problem that the vehicle engine applies power to the wheels which opposes the braking action.

摘要： A device and a method implementable therewith for regulating the driving speed of at least one vehicle, having an electric motor/generator connected or connectable to a drive train for at least one wheel as a function of at least its actual speed and setpoint speed. The device includes a control unit for controlling the torque of the electric motor/generator, an arrangement for driving the electric motor/generator, an arrangement for recording the actual speed of the vehicle and an arrangement for preselecting the setpoint speed of the vehicle. In the device, the electric motor/generator is usable in generator operation to generate a braking torque and in engine operation to generate a driving torque.
